多能源控制系统是混合动力电动汽车的关键技术之一。多能源控制系统需要在保证汽车动力性的同时解决好动力系统能源分配问题。其控制的根本目的是要尽最大可能使发动机在其最佳工作区域内工作 ,以达到减少废气排放和改善燃油经济性的目的。本文根据这个原则展开对串联式混合动力电动汽车 (SHEV)的多能源控制策略的研究 ,提出了一套行之有效的多能源控制策略 Multi-energy control system is one of the key technologies of HEV. The multi-energy control system needs to solve the energy distribution problem of the power system while ensuring the vehicle’s dynamic performance. The fundamental purpose of its control is to try its best to make the engine work in its optimal working area in order to reduce emissions and improve fuel economy. Based on this principle, this paper develops a multi-energy control strategy for a series hybrid electric vehicle (SHEV) and puts forward a set of effective multi-energy control strategies
